    My two children have been a part of the Mt. Calvary Lutheran School family for four years now. I cannot praise the school enough for their academic excellence. Both of my children are in advanced mathematics classes and we anticipate our 8th grader completing Algebra II by the end of 8th grade! The close parental involvement and caring teachers make all the difference. I would recommend our campus to any parent who is looking for a Christian based strong academic program that focuses on each individual child's learning abilities.

    I have a child that attended this preschool. And was planning to have my older child attend K-8. The administrator and principal should be ashamed to call themselves Christians. They couldn't even be upfront to us about our child. We did not appreciate the disparate treatment. Send your kids elsewhere. I am glad I found a better school.

    I have one child who completed preschool and now is in kinder and another child in preschool finishing his last year. Our family loves the school. One main reason we LOVE the school is because my husband and I both feel safe and secure when we drop our kids off everyday and that means the world to us. Another reason is the education the kids are receiveing is amazing. We really love and had a great experience with all the staff in preschool kindergarten and school admisitration.

    I have two children attending this school and could not be happier. As with any school teacher or staff there are bound to be personality conflicts differences of opinion or an occasional occurrence that will offend someone. Bottom line is that my children are getting much more than just a quality education. I enjoy that the children from different grades interact with and know each other by name. Being able to start team sports in 5th grade and compete against other schools in volleyball basketball flag football and track are all great opportunities for the kids to grow. There is a very strong feeling of community between the students parents and staff at this school. I imagine that if you are the type of parent that sends your child to after school and weekend school on top of their standard schooling you may well have a different opinion of your experience. But if you enjoy being part of your child's life and desire that they have a safe and loving environment where everyone staff and parents will go out of their way for your child Mt. Calvary is the place for you.

    Mt. Calvary pre-school is a decent choice overall however I do believe that the teachers should be better skilled in how to handle involved concerned parents questions. Sometimes they tend to be on the defense which may come off as not as forthcoming when they really should be an open book where our children are concerned as it relates to their educational and emotional development. It can be a little frustrating when I ask the teachers a question then they refer me to someone else who refers you back to make a long story short communication could use a some improvement as well. The other thing I've noticed is that they are not real good about getting back to you on things they don't know I hate to feel like a hound just to to get needed answers but this is usually the case. I just want them to do what they say they will I hope this constructive criticism helps both readers and school director and teachers. I'm glad to see more parents speaking out rather favorable or not the pre-school has the potential to be 4 stars or more but they definitely have to listen to the concerns of the parents because if it doesn't work for us it doesn't work for our family

    I have had the opportunity to have been at the preschool for both the old and new director and i must say that i do agree with older posts. They director here is lacking in the knowledge of the position. However i do not agree with the post regarding the teachers. These ladies are some of the best you'll find. They are very committed to the children as well as the work they are very loving and caring. We toured a lot of places bigger/better before stopping at Mt. Calvary but were not impressed. This preschool possess a lot of potential and if you can look past the directors lack of knowledge/innovative thinking and get to know your child's teacher or all of the preschool teachers for that matter; you will truly be happy with the quality of education your child receives.

    I am a parent and very happy with the preschool. What a SHAME to have someone say that the staff wrote the reviews and that the preschool is run down ( so negative maybe it is better that you try another school . Good Luck )

    I am a CURRENT parent of Mt Calvary Lutheran School. I have one child in the elementary school one child currently in his third year of preschool and one child who is scheduled to begin preschool in the fall and we are VERY pleased with the school as a whole. Now seeing as how some parents on this website are bashing the preschool I think I should share my story and do my best to defend these girls. My husband and I had to pull my oldest son out of his previous preschool due to its lack of structure lack of communication in regards to his progress and lack of affection shown towards the children. We luckily came across Mt. Calvary Preschool who had all of these things and much more. After being highly impressed by an informative tour we signed him up and have never regretted our choice to do so. Both of my sons absolutely LOVE the entire staff as well as my 2 year old daughter who only sees them at drop off and pick up. These 7 women are extremely friendly nurturing and hard working and I thank God every day that we found such a great school. Please consider that every family is different and just because 1 or 2 parents weren't pleased doesn't mean you won't be!

    I am glad I choose Mt.Calvary ! It is a wonderful school! MY daughter loves going to school. I disagree about what these parents said. These teachers are caring and loving . I never see teachers work so hard. I know I am leaving my child in great hands )My child has been attending for 2 years. Never had an issue with teachers ever or should I say never had a bad experience.

    My first kid was there starting in 1982 in preschool through 8th grade went on to be valedictorian at DB High then Summa Cum Laude at Princeton then two graduate degrees in France and is now online sales manager for Louis Vuitton in Paris. My second kid started there in preschool through 8th grade went on to be valedictorian at DB High then graduated from Dartmouth then from American University's law school in 2011. My third kid graduates from preschool there this year. Going on 30 years experience with this school with three kids. Results speak for themselves.

    Please don t take your kids to this school. I have had many bad experiences with the teachers pre-school director principle and pastor. I have tried hard not to give up but was not able to because they have communication problem even with the children. I just learned from my son that he had to go party and his teacher told him to wait 3 year-old when he was in tears than she told him to go. I am so glad I took my child out I found a much better school in Diamond Bar. Shop around please before you go to this terrible school.

    I had two attend Mt. Calvary. One went on to an IB program with great honors and well prepared. The other still attends and does very well. We are very proud of the staff ciriculum and results. Great people with devotion to our kids.

    My daughter has attended Mt Calvary Preschool for 2 1/2 years. She loves this school as well as her teachers. My wife and I looked at a tons of schools and this was much better than all of the others in the area. They provide a safe and academically supportive environment. I don't get where the other reviews come from. I have never had a problem and neither do any of the parents that we talk to. I would whole-heartedly recommend them

    Mt. Calvary is always striving for improvement while still maintaining it's core values. The goal is to provide excellent education within a Christian environment. The preschool issues mentioned by parents below are a thing of the past. We have an excellent director for preschool and the staff is very well qualified. The school scores above the national average in all subjects and I disagree that it is below any of the public schools. Kids who have gone to public schools from Mt. Calvary feel that they are not challenged because they are more advanced for their grade level. You should check it out.

    Mt. Calvary is an outstanding school I have a unique perspective being a parent and a high school teacher at D.B.H.S. Mt. Calvary staff is extremely supportive of parents' and children's concerns. The education is excellent. I have had students from Mt. Calvary in my classroom at D.B.H.S. If the student came from Mt. Calvary and had an involved parent in his/her education at Mt. Calvary s/he is doing well at D.B.H.S. I've never a 'poor' student from Mt. Calvary. As far as the writing curriculum goes I think that it is great. Excellent writers must be excellent readers. If your child is not a reader encourage him/her to read. S/he will excel in school. I LOVE the community of teachers and parents and most of all the beautiful Christian education which is reinforced constantly. This school is a blessing and a treasure. Send your kids here!! You'll love it!!

    Many of the previous preschool issues have been resolved. My child's teacher works with him at his level. She listens to his many stories. He can't stop talking about all the great things she has done.

    You can truly get a Christian Education here at Mt. Calvary. I believe in God and am glad that my child can learn about God. I love that my child gets to learn about the Bible at school at the same time she is getting an education. It's priceless.

    There is only one class at every grade. They are very weak in writing and reading. I believe that the average is behide than public school's student of Diamond Bar. Good Luck!

    I completely agree with the parent who posted on March 17 2008. I feel several members of the pre-school staff have no idea how to interact with the children in their care. They speak very harshly to them and I never see any redirection. I don't think my child will be returning next year. Instead I will be looking for a NAEYC accredited school where the staff has gone above and beyond the basics.
